…nothing, including the final scene, is as it seems in this eerie, elegant fantasy…Intricately plotted and richly imagined, this novel holds the attention as inexorably as Incarceron holds its prisoners.
The Washington Post
Kirkus Reviews
A far-future thriller combines riveting adventure and masterful world-building with profound undertones. Finn cannot remember anything before awakening in the vast sentient prison called Incarceron, but he is sure that he comes from outside its hellish confines. Claudia has known nothing but luxury as the daughter of Incarceron's Warden; but she dreads her imminent marriage to the caddish prince of the Realms, which are trapped in a static reenactment of a pre-technological past. In parallel narratives, each discovers a chance of escape in matching crystal keys. Their separate quests gradually intertwine with increasing suspense, cresting in a series of shocking reversals and revelations. Claudia and Finn and their assorted companions are complex and comprehensible, engaging reader sympathies even as they mislead and betray each other. Elegant prose and precisely chosen details deftly construct two very different worlds, hinting at layers beneath the glimpses the tale permits; attentive readers will hear echoes of classic tales, resonant with implications about the meaning of stories, of faith and of freedom. Like the finest chocolate, a rich confection of darkness, subtlety and depth, bittersweet and absolutely satisfying. (Science fiction. YA)
Wall Street Journal
This book is a thriller of the highest order; Fisher could give the show "24" a run for its money with her twists and messed up characters...putting it down took a serious act of will.
Booklist
[B]reathless pacing, an intelligent storyline, and superb detail...With some well-timed shocking twists and a killer ending, this is a must have.
Horn Book
Fisher's dystopic future...is brilliantly realized..reader attention never flags through this elegant, gritty, often surprising novel.
